Watanuki is in a grocery store and asks a clerk for a vitamin drink (this is crossover with another CLAMP series named “Legal Drug.”). When Watanuki buys the drink, he goes over to Yuuko’s shop where Yuuko is lying down, moaning and complaining about her hangover pain. Yuuko guzzles down the drink followed with a glass of water and she is immediately back to her usual self. She then declares that she must go out and that Watanuki must go with her. When Watanuki asks how they’re going to get to their destination, Yuuko answers that they will be walking to Ginza, a place very, very far from there. Watanuki asks how they will get there in time and so Yuuko shows Watanuki a portal she has in her shop that allows her to go to faraway places quickly.
